 ## 一组事件的监听器
 
+### 一个简单的应用类

+```php

+ * @package Inhere\Event\Examples
+ */
+class App

+里面存在跟事件相同名称的方法

+ * Class AppListener
+ * @package Inhere\Event\Examples
+ */
+class AppListener
+{

+    {

+    }
+
+    public function beforeRequest(EventInterface $event)
+    {
+        $pos = __METHOD__;
+        echo "handle the event {$event->getName()} on the: $pos\n";
+    }

+    public function afterRequest(EventInterface $event)

+    {
+        $pos = __METHOD__;
+        echo "handle the event {$event->getName()} on the: $pos\n";
+    }
+}
+```
+
+### 准备运行
+
+```php
+$em = new EventManager();
+
+// register a group listener
+$em->attach('app', new AppListener());
+
+// create app
+$app = new App($em);
+
+// run.
+$app->run();
+```
+
+### 执行
